Abstract
A valve diaphragm for a relief valve may include: a body having a first beaded end and a second beaded end, the first beaded end having a bottom surface and a bulge extending from the bottom surface. The bottom surface may be configured to contact a first portion of a corner of a lower valve body, and the bulge is configured to contact a step of an upper valve body, and the engagements of the bottom surface, the first portion of the corner, the bulge, and the step may be configured to create a fluid tight seal between the upper valve body and the lower valve body.
Claims17
A valve diaphragm for a relief valve, the valve diaphragm comprising:
- a body comprising a first beaded end and a second beaded end, the first beaded end comprising:
- a bottom surface;
- a side surface;
- and
- a bulge extending from the bottom surface and the side surface,
- wherein the bottom surface is configured to contact a first portion of a corner of a lower valve body,
- wherein the side surface is configured to contact a second portion of the corner of the lower valve body, the second portion extending perpendicular to the first portion,
- wherein the bulge is configured to contact a step of an upper valve body,
- wherein the contact between the bottom surface and the first portion of the corner, the contact between the side surface and the second portion of the corner, and the contact between the bulge and the step are configured to create a fluid tight seal between the upper valve body and the lower valve body,
- wherein the fluid tight seal is created such that a single empty space is defined between the first beaded end and the step on a side of the first beaded end opposite the second portion of the corner,
- wherein the body is compressible, such that the step is configured to compress the bulge toward the bottom surface,
- wherein the body further comprises a tail extending from the first beaded end proximate the bulge, and
- wherein the tail is configured to contact at least the second portion of the corner to create the fluid tight seal.
A relief valve comprising:
- an upper valve body;
- a lower valve body at least partially defining a fluid flow path;
- a stem configured to move between the upper valve body and the lower valve body, the stem at least partially extending into the fluid flow path;
- and
- a diaphragm disposed between the upper valve body and the lower valve body, the diaphragm comprising a body having a first beaded end and a second beaded end, the body defining an aperture to receive at least a portion of the stem therethrough,
- wherein the first beaded end comprises:
- a bottom surface;
- a side surface;
- and
- a bulge extending from the side surface and the bottom surface,
- wherein the bottom surface is configured to contact a first portion of a corner defined in the lower valve body,
- wherein the side surface is configured to contact a second portion of the corner, the second portion extending perpendicular to the first portion,
- wherein the bulge is configured to contact a step defined in the upper valve body,
- wherein the upper valve body and the lower valve body are arranged such that the contact between the first portion of the corner and the bottom surface, the contact between the second portion of the corner and the side surface, and the contact between the bulge and the step are configured to create a fluid tight seal between the upper valve body and the lower valve body, and
- wherein the fluid tight seal is created such that a single empty space is defined between the first beaded end and the step on a side of the first beaded end opposite the second portion of the corner.
